Default Which PSU? - 05-13-2013, 05:49 | posts: 1,403

As the title says, I want some help on deciding power supply. My budget is $100-$150, I would like to keep it as low as possible since I don't game much nowadays and I'm not into overclocking and SLI/CFX. Modular is not necessary. And 750W should be fine in case I decide to go SLI/CFX right?

Is this a good choice? - http://www.newegg.com/Product/Produc...irtualParent=1

if you do decide to go SLI- that 750W should be fine. if you dont think you will go SLI you do have room to save some money and drop to a 600W psu.

How is that ironic?

@ jmpnop

There's a Shell Shocker on an XFX 650W semi modular. Only $40 AR, sick deal. It's 80+ bronze, but it has the cables and the power for almost any dual GPU setup, especially considering you don't really OC. And you're unlikely to go SLI/CF anyway, so I don't see the point in blurging $60 more on a 100W more powerful unit.

If you don't run your machine 24/7 nor running heavy tasks, I'd suggest to drop to bronze TX Corsair.

I was thinking about getting SLI or crossfire and bought this 850HX monster. I don't even use half of it, yet HX is more electricity usage efficient.

If you after saving, I'd strongly suggest to go with 650TX.

No really need to get dirty with SLI or Crossfire. There plenty of strong single GPUs around.
I am pretty sure 650W would be enough for holding overclocked CPU and decent GPU.

sverek, the XFX unit I linked is performance-wise identical, but $30 cheaper, semi modular and has more PCIe cables. Absolutely zero reason to go with an outdated TX650 V2.

I had Corsair TX 650 and 750 in mind, is the XFX one better? I'll be using this PSU for my next build, 650W should be fine in case I decide to OC CPU/GPU right? Or should I go 750W which would also give me the option of SLI/CFX? I'm looking at Intel i7/GTX 770-780 for my next build.

The XFX one is indeed better, given the extra connectors and semi-modularity.

650W is more than enough if you OC the CPU and GPU. It is also enough for SLI/CF with mild to moderate OC.

Depends on the GPUs you will use for SLI/CFX. If it 2 strong GPUs like 780, I don't think even 750W will be enough for stable running.

If you sure you going for SLI/CFX, I'd suggest to be safe and go with 850W HX(silver). This way you have headroom for overclocking and stability.

PSU is not something that being changed as frequently as mobo or cpu or GPU. And you planning on running PC 24/7 or running heavy tasks, good PSU should pay off (with time).

If you going just for gaming and not planning on expanding rig, XFX 650W would be the sweet PSU, as lehtv said.

I think I'll stick to single high-end gpu for now. And I use the computer mainly for gaming, So the XFX one should be fine.

Thanks for the help guys, I've decided to go with XFX 650w

I missed the deal on that XFX PSU, I saw Corsair HX 750 and Seasonic X-750 for $105. Which one to get?

http://www.newegg.com/Product/Produc...irtualParent=1

http://www.newegg.com/Product/Produc...82E16817139010

Can I get something better for around the same price (less than $150)?

The X-750 is actually $90 after rebate and promo. Incredibly good deal, grab it. You probably will never need that much power but what the heck, it's among the best 750W units money can buy. I've never seen this unit's price so low, even the X-650 would be a no brainer at that price!

I can actually spend upto $150. Is there a better one or should I just go with X-750? And what about Corsair HX 750?

No, there isn't a better option. The X-750 is for all intents and purposes the high end, there is no higher end. There are only slight (read: irrelevant) improvements in efficiency and voltage regulation, e.g. Seasonic's Platinum units, but they're the same tier, so to speak.

At this point, I believe the deal on the X-750 is over. If you didn't jump on that, you're not going to find a better deal pop up any time soon.

HX750 is manufactured by CWT, not by Seasonic. But feature wise it is very similar - Gold efficiency, fully modular, semi-passive fan, highly reliable.

If you plan on going for the Seasonic x-750w i believe:

Is the same psu but might be cheaper, worth checking out ( i plan on buying it)

My psu. Doesn't come with braided modular cables though. Keep that in mind.

They look better and should be more durable and easier to manage. Not a biggie in my books, I'm very happy with my psu anyway. Braided cables can be purchased separately if needed (I won't bother).

They're not braided but a flat ribbon type as you'll find in the top XFX PSUs, (which XFX may have deemed a 'higher end' feature). All other XFX units down to the cheapest models have braided cables.

oh ok, didn't know that these flat ones were used only on their top models. so how come xfx deem them "better" than braided cables? what are the advantages?

Flat cables have the advantage that they are thinner, so cable management can be easier, especially in tight spaces. Spare cable lengths can also be stored away tidier. The disadvantage is that you can't bend the cable too much width wise, only length wise, whereas braided cables can be bent whatever which way.

TBH, I dont see any advantages at all. Maybe XFX think they look sleeker or cooler I dont know.

yeah, I guess they have pros/cons. flat ribbon is easier to manage behind the motherboard tray, braided looks better and I assume should be more durable, although once you set up your cables, they will last forever no matter what. Your psu will crap out on you well before the cables go bad.

Either way, I'm happy with my XFX and I would recommend it. Mine cost me 111 which is a good price. the Corsair HX 750 gold was a few quid cheaper, but my last PSU was a Corsair and I wanted something different if that makes any sense. Either way, they're both great PSUs.
