intel i7 2600 3.4ghz
500gb sata2 hdd
intel h61 chipset socket 1155 mobo
4gb 1333ghz ram
HD6950 graphic card


What i need to know is what is the minimum power supply could i have for all these components and what make and model psu should i buy. I am looking to buy from take2.

Minimum:

Cooler Master GX - 550 Watt Power Supply

but rather get:

Cooler Master GX - 650 Watt Power Supply Unit

Terrible product.

Their conclusion:

The Cooler Master GX 650W is a mediocre power supply for couple of years ago, and an outright failure today. The Build Quality of the unit is nothing to write home about (unless it is a warning), the topology is old and outdated, and the exterior is flash over substance. Coupled with this we have mediocre voltage, poor by today's standards efficiency, and out of specification DC Output Quality. One upping this poor showing is that fact that the unit was completely unable to complete our load tests at 100v AC input. That makes the GX 650W not just a failure by our standards, but rather a double failure and an ugly one at that.

While testing that PSU died on the reviewers. That is as bad as it gets. Absolute rubbish product.

It doesn't even have a good price. I haven't followed PSUs for a while now but I can spot the bad brands. One of them is Cooler Master. They make a few good PSUs but for the most part it's cheap crap.

Well with all that said...

A minimum 650w would be the answer here...

You can look at a number of PSU's in that wattage range..This site might give you a good idea of a good 80 plus PSU..
 
Look at something from Corsair. They're pretty much THE brand to go for these days, when it comes to PSUs. They have some reasonably priced models as well. Don't skimp on quality here. A poor quality PSU can end up blowing everything else in your system.
 
Even a Corsair CX500 would suffice.

I'm just wondering why you're going for the expensive i7 2600 and a cheap HDD & motherboard!

Rather go for the i5 2500k and like an Asus P8P67-M motherboard (or any other P67 chipset motherboard that isn't too expensive), and an aftermarket cooler like the CoolerMaster Hyper 212+ / Cogage True Spirit with a Socket 1156 bracket (seeing that the Socket 1155 uses the same mounting bracket).

If your brother is going to run simulations, or anything that would require lots of threads, then it would be worth it to go for the i7 2600k, but it's not worth it for just gaming!

If your bother is going to overclock, then it would be advisable to go for one of the PSU's that PostmanPot suggested.
 
The only decent PSU's that Coolermaster makes are the Silent Pro series, and it is very expensive.
For that reason PostmanPot recommended the Corsair CX600, GS600 and TX650 PSU's.

Another PSU that is worth looking at is the Antec HCG 520W.

I can vouch for that. The reason for them being so expensive is mainly because they have modular cable management.

Can not complain about the 850W one that I have...Works like a charm..

It's overkill. 500W PSU is enough for the specs above. Might even get away with a Corsair 430W PSU. But to play it safe get at least 500W.

From above you'll notice: You could even run a AMD Radeon HD 6970 on a Corsair 430W PSU. The chart above is total system draw AT THE PLUG, not just GFX power draw and it is measured at the plug so efficiency must be taken into account (eg. the actual load is less than in the chart).

The system they used has a 130W TDP CPU which is 35W more than the 2600K (95W TDP). Therefore even a Corsair 430W PSU will easily cope.

Rather pay ±R100 extra for the TX650 IMO because it's a better PSU but more importantly has a 5 year warranty (compared to the GS's 3 year). But ja, even the CX500 will be fine, it's unnecessary to spend more.
 
what do you think of the thermaltake trx 650m psu. Is thermaltake a good make because it is R900 at pczone and it is a modular psu
