Visiontek dedicated PSU

[itadakimasu]

I bought an as-is computer last week w\ a q6700, 6gb, 700w psu for $200. The guy said it wouldn't boot... i finally got around to messing w\ it yesterday. Pulled the cmos battery and it booted fine ^^

anyhow... it has this thing in the 5.25 bay and I had no idea what it was, it had a power plug and the front part had visiontek logo on it. anyhow, little resarch and i found out what it is :

dedicated psu for video cards... I had never seen this before. I just thought it was a pretty good idea for certain situation, one of them being Dell systems that come w\ highend specs except for the PSU and video card !

I looked on the completed items on ebay and best buy's outlet has been selling these for $30-40... Just thought it was a pretty cool idea for certain setups if completely replacing the psu might not be the answer.

I don't recommend this option. Its like a patch-up job due to a shortfall of the original power supply. Its best to upgrade the entire power supply to accomodate the added load.

A critical load such as Video card (i.e. GTX 285)..powered by 2 different power supply module of different make. Part of the video card power is supplied by the oroginal PS through the PCIE. The external PS on the same video card powered by Visiontek PS. In reliaty inside the video card 2 VDD will exist... One from the PCIE and the other from the external supply. These 2 VDD can never be the same in real world.


By design its not a clean solution with respect to power and noise management. Two different switching supply of different make will behave differently on certain condition.

This is cutting corner by DELL...

^ I agree with your reason for disliking the addon psu, but it's not a Dell corner cutting thing. They won't add it on for you, it's something the consumer decides to purchase and install after the fact.

I had tried that option with a 400 watt juice box. It sucked. I took it back and got a good power supply and never have considered doing that again. There's no substitution for getting the correct power supply...

I only made this thread because i'd never heard of such a thing until last week...

And my first thought of a useful application for it is dell systems because alot of them ship w\ puny psu's and video cards, and require more power in order to upgrade the video cards.

I have a XPS 8300 that I bought last year. It came with a Radeon HD 5670. Since that isn't that great of a GPU(games have been a little laggy) I wanted to get the new Radeoon HD 7850. But when I looked it up on dells compatable GPUs for my PC, it they werent compatable. So then I talked to a DELL representative and found that if you buy a Visiontek dedicated power supply, I can use a HD 7850 because my stock PSU was only 460w and it voids the warranty if you change the main/built in PSU. But she clearly stated that if I buy the dedicated power supply then it DOESN"T void the warranty and I can then get a Radeon HD 7850 or anyother GPU I want. So in the minds of people who dont want to void their DELL warranty, this is definately the best solution😀

For those of you who will complain about reopening an old thread, this was one of the only threads that came up when I searched about this topic. I'de rather post on a page people will most likely see rather than a more recent one that's 5 or 10 pages down the search results.
