New High end PSU needed.

[Newt]

Hi, I’m looking into a new PSU to replace my current one as it's faulty.
I want a high wattage PSU to help future proof me as I’m sure I’ll be adding another graphics card and more in the near future. I've used a PSU calculator to work out my future build may be using up too 1050w plus capacitor ageing.

There are 4 that have caught my eye though I’m not sure which will be the best to get they are as follows;

Antec TPQ-1200 1200W
CORSAIR Professional Series HX1050 1050W
OCZ ZX Series 1250W 80 Plus Gold Modular Power Supply
Silverstone Tech. SST-ST1200 Strider 1200W Modular Power Supply

My rig;
Asus p8p67 Pro
Intel 2500k
Asus GTX580 Direct cuii
4x2gb DDR3 RAM
1TB HDD
DVDRW drive
NZXT Phantom

Depends on how much overclocking you're doing on your i5 but that 950w should be fine.

One advantage to bottom mounted psu cases is that if you've got the fan facing down, then it's pulling in cold air from below not sucking in warm air from the cpu and back of the graphics card.
This is important esp in capacitor ageing as heat is a key factor in capacitor ageing, as is having 105c rated caps instead of 85c rated caps (which the TX should have)

Thanks Pob.
The thing is I’m replacing the TX950 but as the retailer don't sell it any more they will offer a replacement though I have the option to pay a little more and get a more decent supply. I thought these ones looked best but I can't decide on which one. I defiantly want modular though. The reason I’m aiming so high is I’ll probably get another GTX 580 and I’ll be water cooling too so overclocks may suck up a fair bit of juice.

Yeah the phantom is bottom mounted and i can feel a massive difference in the temp of the exhaust from my cluttered old coolermaster elite 334.

I read a review saying the Silverstone was very good but the OCZ seems to also be a strong contender.

Having used both of these I can confirm they are what I would personally choose

CORSAIR Professional Series HX1050 1050W
OCZ ZX Series 1250W 80 Plus Gold Modular Power Supply

Even a Corsair HX850 would do fine, or any decent 850w

[Pob255]

All 4 are decent psu's

An 850w should be ok, although it could be pushing it if you overclock the i5 2500k
A single gtx580 can use up to 310w by itself although under normal gaming it's more around 225w

If it has to be one of those, get the cheapest one. They're all decent according to tests. As far as power requirements go: I have the old Corsair HX1000 and run a Q9550 @ 3.6GHz, a GeForce 275GTX, 14 hard drives, an SSD, 2 PCIe raid cards and 8 x 120mm fans - with power to spare.

My choice would be the Corsair, if only because mine has performed flawlessly.
