Want more from your PC? Upgrade the part that matters.
More storage? Better gaming performance? Less waiting? We’ll check what your current system can actually benefit from before recommending parts.
Pick the upgrade goal.
Start with the result you want, not the component name.
SSD or NVMe upgrades can make an older system feel dramatically more responsive.
Check it with Signal Scan →Make sure the upgrade is actually worth it.
Compatibility is only half the job. We also look at the current bottleneck, power, cooling and the rest of the platform.
Compatibility, interface support, available slots and whether storage is the real bottleneck.
Capacity, speed, channel layout and motherboard limits before buying memory.
CPU balance, PSU capacity, case clearance and target resolution before choosing a graphics card.
Case airflow, fan layout, cooler fitment and whether heat is actually holding performance back.
Check, choose, install.
We look at the current hardware and what is actually limiting it.
We recommend the part that gives the best practical improvement.
After installation, we check stability, temperatures and performance where relevant.
Upgrade with a reason.
Not every PC needs new parts.
If the platform is too old, the PSU is unsuitable or the upgrade won’t give you much value, we’ll tell you before money gets spent.

Common questions
Can you supply the parts?
Parts can be sourced or quoted where available. Hardware pricing is confirmed separately before purchase.
Do you build complete PCs?
Full custom PC builds are currently paused while VoltTech develops reliable supplier and pricing systems. Upgrades to existing systems are available.
Will you tell me if an upgrade is not worth it?
Yes. If the surrounding platform would limit the value, we’ll recommend the better option instead.
