Introduction:

Choosing a good PSU can be one of the hardest things when custom building a new computer.  Many companies rely on brand name alone in order to sell PSUs.  Stability under load is what is really important if you're a gamer as one of the last things you want to happen is for your system to crash when you're playing the final round for cash and prizes in a tournament.  Today we are looking at the Tuniq Potency 750W PSU and are going to see what kind of a step-up this is from the last Tuniq PSU we looked at - the Potency 550W.  Both of these PSUs are "SLI-Certified" but the Tuniq Potency 750W has a total of four +12v rails while the 550W little sister only has two +12v rails.

 

Packaging & Bundle:

The Tuniq Potency 750W PSU comes packaged in a nice box that shows a picture of the PSU in the box as well as the main specs and features of the unit.  Once again, while the PSU claims to be "SLI Certified" the sticker on the box only states that the PSU is "SLI Ready" - we'll explore that in more detail later.  Tuniq has listed the PSU specs on the back of the box and this is great for the consumer as they can see exactly what kind of output to expect on each of the +12v and +5v rails.  There should be no surprises when you get it in your system.

A 750W PSU is probably one of the most practical PSUs for people wanting to build a high-end system with two graphics cards.  It will have enough power to keep most systems rock stable and yet won't break the bank.  It should fit nicely for many users without being overkill.  This 750W PSU comes in a standard ATX form factor and should fit in pretty much every case available.  It comes packaged with everything you need to get going and even includes a few extras to keep this non-modular PSU tidy inside your case.  Along with the standard power cord and screws is a bit of a product manual, screws, zip ties and a Molex "Y" adapter that has male and female Molex connectors.

Tuniq Potency 750W First Look:

This PSU has a pretty standard appearance for today's PSUs.  It is cooled by a large 140mm fan that spins quite slow and is very quiet - near silent under all circumstances.  We couldn't detect any additional noise to the system when we added this PSU.  The backside has the traditional honeycomb grill over the entire unit.  There is a power switch and the standard PSU cable connection.  This PSU is auto switching and can operate between 100v and 240v so it should work in pretty much any country with 50Hz to 60Hz power.

Tuniq has opted out of the modular design and has all of the cables hardwired to the PSU.  They are sleeved with nice flexible material and all of the leads are quite supple.  When bundled up for shipping the cables look quite manageable, but when they are splayed out prior to installation, you get an idea of the rat's nest that has to be managed.  This can be difficult in smaller cases and is why I love modular PSUs now more than ever.  However since Ultra Products filed lawsuits for patent infringements related to modular PSUs, companies that market modular units have to pay a royalty to Ultra so that is why we are seeing more and more non-modular units like this one from Tuniq.
