First Self Build Desktop :)

Postby henrybutt » 11 Aug 2009, 03:38

Hi All,

I have recently decided to build my own desktop PC after being offered some freebies for evaluation :). As this is my first self build, I have little knowledge of the best components etc for it and whether everything is 100% compatible. I would be grateful for any advice that anyone can give!

Here is the current setup I am considering:

- ZOTAC 9300 Motherboard (FOC)
- Intel Core 2 Quad Q9550 (£150 + VAT)
- Coolit Domino A.L.C (FOC)
- Corsair XMS2 4GB DDR2 RAM (£38 + VAT)
- ZOTAC GeForce GTX 285 AMP 1GB (FOC)
- WD Caviar Black 1TB 7.2k rpm HDD (£58 + VAT)
- Corsair TX 650W ATX2.2 PSU (£64 + VAT)
- Hiper Anubis Case (£56 + VAT)
- LG CH08L S10 Blu-Ray Reader (£70 + VAT)
- Akasa 12cm Blue LED Case Fan (£8 + VAT)
- KWorld DVB-T 210 TV Card (£23 + VAT)

With a Viewsonic VX2260WM 22" Widescreen FUll-HD Monitor (£150 + VAT)

= £615 ex VAT
= £708 inc VAT

Thanks
Intel Core i7 920 @ 2.67GHz | Asus P6T Mobo | 6GB DDR3 Corsair Dominator RAM | 1TB Samsung HDD (7200rpm) | Zotac GTX 275 | Aerocool Touch V12 Fan controller | Corsair H50 Cooler | Lian Li PC60FW Case | Sony Blu-Ray Reader

Henry I had a Kworld, usb Video capture device, and it was pretty poor to say the least, might be worth considering a Hauppauge device over that, I eventually got fed up with jittery video transfer and bought an express card hauppauge and the quality was far superior. Just my exeience with a Kworld device, their TV cards may be better...

1000w is a bit high ras
the psu may be just enough as that is a good psu which I had in my previous setup but probably you should go for higher maybe 800w?!

I would say 800w is suffucuent, no one really needs 1Kw but its good to boast about.

Or if running a lot of graphics cards, my i7 system (2.93Ghz) with 4850, dual optical drives, 8GB ram, two hard drives, PCI-E soundcard and wireless card is running on a 375W PSU.

375W?

That seems ridiculously low!

I would have said that a 1Kw is probably a good idea if your running 3 graphics cards, but your spec makes me wonder if a 6-700W would do it.

Anandtech are pretty good for doing power consumption tests on their systems, even allowing for inefficiency on the power supplies as long as it's a decent PSU it doesn't need megawatts of power. I used to run my 9700 pro system on a 175W PSU and the AIW 9800 pro on a 200W SFF PSU.

I'm with ras, go big to begin with, the components will only draw what they need anyway, the larger power supply would have superior cooling and wouldn't need to run so close to its maximum output so would probably end up running cooler, quieter and more efficiently. No doubt more and more will creep into the case as Henry gets donated parts to 'test' so the extra wattage will come in handy! :D

Nope, there's plenty of lower power PSU's that run quiet, cool and with very high efficiency.

Power supplies run most efficiently when they are at 60% of their designed load. So its far better to have a power supply that is ample for the job raher than one that can just manage it.

As I said, there are lower power PSU's that have high efficiency - one of the BFG 550W units loses 2% efficiency increasing the load from 50 to 100% load at which point it's still more efficient than rivals running at lower loads. The Silverstone 400W runs at 87% efficiency against 88% percent efficiency for the 550W running at 50% meaning in reality there wouldn't be any difference. It is worthwhile having some overhead for expansion although people seem to go a bit overboard.
