8 pin or 4 pin??

**p2x6ftw** · October 17th, 2010, 10:52 AM

Hi,

Im building a new computer with the specs:

ASUS Crosshair IV Formula Mobo
AMD PhenomII X6 1090T
4x1GB Corsair DDR3 1600MHz RAM
nVidia GeForce 8800GT

My questions:
1. The cable from my power supply if 4 pin. Do I need 8 pins?
2. If so, can I use an adapter?
3. Will using an adapter limit the processor in any way?

halp! thanks in advance!

Whats the make and model of your power supply?

You can use the adapter with no issues but I'm wondering why you have a new build and have a psu that doesn't already have an 8pin plug?

It's a "colors-IT 650W 12cm silent power supply". It's new as well, which is why I'm unsure.

Well honestly I wouldn't recommend using that PSU to begin with. You should spend the extra money and get a PSU from a reliable reputable company. I can't even find any detailed specification information on that unit. That tells me two things its likely a piece of junk from an off brand company and its not widely used by anyone that would know enough to post the info.

Hate to say it but it always amazes me that people will drop hundreds (or thousands) of dollars on a system and want to buy the cheapest PSU out there when that single part is potentially the most important part of their rig.

Really? They don't look like a knock off. Better packaging than some big brands, I tell you. Reviews are good as well. Any particular recommendations? Thanks.

this is a review with some details off amazon:

I thought I'd give you my verdict on this PSU. Excellent! I was looking to spend £80+ on a 650-750W PSU but after reading the reviews and although worried about its price compaired to the competition, I can absolutley recommend this!

Just in case you were wondering, "Colours-IT" must be the same manufacturer as "CiT" as mine came boxed in a CiT logo. Further research looks like they are one and the same.

I was delighted to see that my "750W Gold 12cm Silent Power Supply" has dual 12V Power Rails (not mentioned in previous reviews).

Here is the Power Breakdown:

+3.3V @ 30A
+5.0V @ 30A
+12V1 @ 24A
+12V2 @ 24A
-12V @ 0.3A
+5Vsb @ 2.5A

Leads supplied (as some reviews showed some differencies):

1 x P4 4-pin 12V Motherboard connector
1 x 6-pin PCI-E connector
1 x 20+4-pin main Motherboard connector
2 x SATA connectors (from 1 lead)
1 x Floppy connector
6 x 4-pin Molex connectors

If you are like me and have a motherboard with a P4 4+4 socket, I purchased a 4pin & 4pin molex -> 8pin connector StarTech.com 4 Pin to 8 Pin EPS Power with LP4 Cable Adapter - Power adapter - 4 pin ATX12V (F) - 4 PIN internal power, power 8 pin EPS12V (M) - 15.2 cm: Amazon.co.uk: Computers & Accessories rather than the standard 4pin to 8pin connectors that are out there. Simply to spread the amperage over another feed.

Voltages using Everest reported as being very stable. 12.3V Idle and ~12.1V under load. So no problems to report.

Noise is no louder than my silent collmaster 12cm PWM fans that I have.

All in all, very happy with this product!
(Rated 5 stars)

Not sure which version of the 650 you have, the gold or the black? But after seeing the CiT info I finally found a site with what should be the tech specs 650 black - 650 gold Those specs don't look bad but even a bad psu can boast good specs.

Really? They don't look like a knock off. Better packaging than some big brands, I tell you. Reviews are good as well.

Yeah the packaging is what makes the product

don't put much stock in that! As for reviews I couldn't find any from any real sites, these seem to be a UK only product so its hard to find much if anything about them. I don't put much stock in Amazon reviews and even less so when the product only has a few reviews. That right there tells you most people stay away from that product.

As to suggestions I tend to stick with the suggested brands from this thread Power Supply Info Antec, OCZ, Corsair ect

A 750W unit and thats all it is putting out? Just looking at those low +12v rails is enough to make me recommend buying a better unit.

The Corsair 750W I'm running right now, puts out a single 60A +12V Rail, just for reference, thats 720W's of its full 750W Rating.

Oh, and has the 20+4 Pin Main ATX connector, as well as the 4+4 Pin (or 8 pin) Auxiliary ATX power connector as well.

Add to that 4 6+2 pin PCI Express connectors. 8 SATA, 8 4pin Molex, and 2x Floppy Power connectors.
